Instruction Set Summary
3.1.2 Integer Arithmetic Instructions
The integer arithmetic operations include four basic operations: ADD, SUB, MUL, and DIV.
They also include CMP, CMPM, CMP2, CLR, and NEG. The instruction set includes ADD,
CMP, and SUB instructions for both address and data operations with all operand sizes valid
for data operations. Address operands consist of 16 or 32 bits. The CLR and NEG
instructions apply to all sizes of data operands. Signed and unsigned MUL and DIV
instructions include:
3-6
NOTE: A register list includes any combination of the eight floating-point data registers or any combination of
